title: Actively Q-switched compact Yb:YSGG laser generating 3.1 mJ of pulse energy.
abstract: An efficient compact Yb:Y(3)Sc(1.5)Ga(3.5)O(12) garnet crystal laser actively Q-switched with an acousto-optic modulator is demonstrated, producing stable pulses at repetition rates ranging from 1 to 30 kHz. With 10.8 W of pump power absorbed, an average output power of 3.1 W at 1025.7 nm is generated at pulse repetition rate of 1 kHz, with a slope efficiency of 46%. The resulting pulse energy, duration, and peak power are 3.1 mJ, 23.9 ns, and 130 kW, respectively.
